in the arteries occurring when the heart contracts. The lower reading (diastolic pressure) shows the lowest pressure in the arteries, which occurs right before the heart contracts. Blood pressure readings are written with the highest value first, then the lowest value. Readings of 120/80 are considered to be normal, with high blood pressure being defined as a systolic pressure which is 140mmHg or more at rest and a diastolic pressure which is 90mmHg or more at rest. Only a patient’s physician is qualified to determine whether the readings obtained are normal for that person.
